Description:
Large peridotite massifs are scattered along the 1500 km length of the Yarlung–Zangbo Suture Zone (southern Tibet, China), the major suture between Asia and Greater India. Diamonds occur in the perido

Description:
A unique set of diamonds with a ‘milky’ optical appearance from the Rio Soriso placer deposit in the Juina area, Mato Grosso, Brazil was studied by combined transmission electron microscopy (TEM) and
... More

Description:
For more than 20 years, the reported occurrence of diamonds in the chromites and peridotites of the Luobusa massif in Tibet (a complex described as an ophiolite) has been widely ignored by the diamond

Description:
Nitrogen isotope values from mantle diamonds are a commonly used tracer in the quest to track volatiles within the Earth's mantle through deep time. Interpretations of this isotope data are valid so l
... More

Description:
The carbon and nitrogen isotope values of mantle xenoliths and xenocrysts are used to trace the cycling of volatiles in the deep Earth, for example, to place empirical constraints on the origin of dia

Description:
Mixed-habit diamonds are a special type of crystal that form by simultaneous growth by two different mechanisms; octahedral and cuboid growth. This type of crystal growth is known to preferentially pa
... More

Description:
Fourier transform infrared mapping of diamonds can reveal detailed information on impurities, with a spatial context. We apply this technique, combined with in situ isotopic analysis of carbon, to the
... More

Description:
We report the results of a high-pressure high-temperature (HPHT) experimental investigation into the deformation of diamonds using the D-DIA apparatus. Electron backscatter diffraction (EBSD) data con

Description:
Developments in technology are making the application of Fourier Transform infrared (FTIR) mapping to the study of minerals more feasible. In the case of diamonds, IR spectroscopy provides a simple me

Description:
Mixed-habit diamonds are a relatively understudied subset of samples, considering the amount of research that has been carried out on these vessels from the mantle. They exhibit periods of growth duri
